[TowerTalk] Tower Build

[Bryan Swadener]

For my setup, as I described, there is no needfor a tilt plate. And, it would still not give me accessto the vertical on top of the mast above my F12C-4XL yagi. With my setup, I have access to ALLantennas with both feet on the ground. 
The clamp assembly I use to hold the yagi fromrotating while tilted consists of a piece of anglestock and two U-bolts.
YMMV

Take a look here http://www.nn4zz.com/tiltplate.htm or Google for antenna hinge. I built one, works great.
